it known that 1, MA1-WAN Tnoranosni, a

citizen oit Russia, residing at New Britain,

in the countyof llartliordand State otGoIr necticut, have invented certain new and use- 0111 '3 t" `W`d `ll fl`l iu mproi tmen s in intim s, o wncithe Jfollowing is a specification.

ll/ly `invention relates to improvements 1n windmills, and the object of my `improvei Fig. 5'is a sectional viewon the line er of Fig. 3. i i

Fig. 6 is a fragmentary front elevation ot a portion of the windmill.

Fig. 7 is a sectional view on the line et Fig. 6.

My improved windmill comprises the windmill proper 10 positioned in a vertical plane, mounted by its center on the horizontal shaft 11, and operatively connected to the vertical power shai't 12, the latter being supported in the head or Yframe 13, and means for bodily shifting the position of the windmill 10 'so as to adjust the same tor the purpose et changing the wind etliect, operated through the medium ot the vertical adjusting shaft 141.

The traine 13 is ot skeleton construction, oit square ci'osseection, having at the corners angle bars 15, which are cross-connected by tie pieces 16, and having at the top a top-plate 17 of circular torni generally and provided with a laterally extending ear 18. rllhe plate 17 has a hole at the center of the circular or body portion for the power shatt 12 and there is a hole at the junction ot the said body portion and the ear 18 tor the adjusting shaft 141.

rl`he powaI shaft 12 extends upwardly through the top-plate 17, has mounted on the extreme upper end a bevel gear 19, and between the said bevel gear 19 and the topplate 17 and resting en the latter is a plategear 20.

The adj listing shaft lll extends through -the plate 17 and has mounted on the upper "Speeicettion (if '.tietteiis Patent.

`lend a `pinion 21, resting on theplate 17 and accordingly in the sameplane as theplategear "20, and `which cooperates with theteeth in the t peripheryoit the said plate=gear 20.

At the lower `end ot thepower sha'lt 12" mounted aigear thatfserves as the meanslor connecting' to the work.

1Mounted on the upperside ot the gear plate 20 is a `pair otl bearings 23f1to1' the `windmill shatt 11, inspaced relation, one" .on eacheideo'l the center, andlot suthcient height to support a bevel gear or pinion 24:, mounted on thefsaidwindmill shaft 11, so as to cooperate with the bevel gear `19 on the power shaft 12.

The windmill; 10 is ot special construction, comprising a circular back plate 25, mounted on the windmill sha'l't 11 by means ot a pairot hubs 23, one on each side, and having each a tlai1ge`27iol circular Ltorm bearing `zigainst thewplate 25, and secured `by bolts that pass through the said tlanges 27 and th e plate 25 interposed therebetween. 'lhe periphery et the plate 25 is bounded by an angle etrip 29, bent `into circular torni.

tln he outer tace oit the plate 25 is mounted a set oit blades or `Janes 30 oll special form, extending from the tlange 27 of the outer hub 2G to the peripheral angle strip 29.

The blades 30 are oit shoe material ot appreciable depth, and are bent so as to form three sections ot equal length, comprising in each case the inside section 31, the outside section 32, and the intermediate connecting section rlfhe innermost end 31 oit the base ot the vane, adjacent the Vflange 27, and the outermost end 35, are in line with a radius, and the intermediate section 33 is parallel to the same radius, and the length ot the venes 30 is such that the said intermediate section 33 will in each case be appreciably ott-set relatively to the said radius, due to the bends 3G at the junctions of the adjacent sections, as shown.

is described, the vanes 30 have a genen ally bowed form, and the inclination ol the said vanes 30 relatively to the back plate 25 is in the same general direction as the bends 3G relatively to the intermediate section 33, wherefore the 'structure ot the said vanes 30 ie such as to cooperate with the bach plate 25 to term a bucket suitable to receive a power impulse effectively from wind 'from substantially any direction between extremes that would be determined generally by the direction of the plane of the back plate on one side and the plane of the 'inclination of the vanes 30 relatively to the said back plate 25 on the other side.

As a support for the vanes I provide an angle strip 39, the inner iiange 40 of which is secured to the back plate 25 and the Vouter flange 41 of which is secured to the vane 30, at the lower edge portion thereof. The two iianges 10 and 41 are disposed at a right angle, and the body portion ot' the vane 30 is bent relatively to the said lower edge portion suitably to provide for the 4.proper inclination relatively to the back plate 25, as shown in Fig. 7.

By shifting the windmill 10 bodily the same may be brought to a position for effec- Y tive operation between the limits mentioned,

and -to reduce the power obtained for a given direction of the wind the windmill may be .turned relatively to theV wind to one side or the other of the limits described. To eiect such turning of the windmill 10 the adjusting shaft lt is turned to obtain the adjuststructure shown and described is elicient in operation and the construction is simple and substantial, such as is adapted to withstand hard usage.

I claim as my invention l. A windmill comprising a circular back plate, a hub structure connected to the ccnter of the said plate, and vanes mounted on one face of the said plate in a generally radial position, the said vancs being formed of sheet material, having a bowed forni of structure formed by a plurality of bends of the said material, and being inclined nt an appreciable angle relatively to the said back plate.

2. A windmill comprising a circular back plate, a hub structure connected to the center of the said plate, and vanes mounted on one face of the said plate in a generally radial position, the said vanes being formed of sheet material, haring a bowed form of structure formed by a plurality of bends of the said material, and being inclined at an appreciable angle relatiif'ely to the said back plate, the said Yanes extending from adjacent the middle of the said back plate to the periphery, and the said sections being oil equal length.
